Need advice on a couple things for heating my home.
I currently have a Weil Mclain boiler that is about 20+ years old, but unfortunately it has a leaky exchanger. I want to replace this OIL burner boiler, but not sure if I would stay OIL or go LP (no nat gas where I'm at). Here are a few questions I have.....
First some info....
House is roughly 900 square feet, 1.5 stories. Cast Rads on both floors (total of 5 rads), one zone. I think the boiler is currently 160,000 BTU's (which seems to be too much). Hot water boiler, not steam. Currently have domestic coil.
1.) I have been kicking around going to LP but the cost of LP and Oil are about the same when you think of the BTU difference, however, in my case I think maybe I can get away with 100,000 BTU's or so instead of having 160,000 BTU's for this small house?
2.) It's getting a bit late in the year for doing a complete swap out to LP as I would have to get a tank, or two, run the line, etc.... Should I just put in a used OIL boiler for now? I see a lot of used ones around (some being only 10years old) for around 500.00. They mostly were replaced because people went to NatGas or LP.
3.) Can I exhaust an LP boiler out thru my chimney? The chimney is about 18 - 20 ft high.
4.) Anyone know about any rebates going on for OIL or LP installs?
I think that about does it for now.
Probably a really stupid question.....
If I'm WAY over BTU ing this house now at 160,000 BTUs and I reduce to around 40 - 50,000 BTU's Logically I should be using a LOT LESS oil, correct?
Also, since I'm heating using cast-iron radiators do I need more output BTU's? I would need about 40,00 - 50,000 output BTU's?
Can I figure out what BTU's I need to purchase?
I'm ready to buy now, I've decided to stay with OIL for now. Can anyone tell me a way to figure out my BTU's?
